The UK stands among the leading countries in Europe, spearheading the transition to a carbon-neutral future. Its aim is to achieve a Net-Zero economy by eliminating all GHG emissions by 2050. PAS 2035 is a comprehensive guide to retrofit standards in the UK, introduced following the recommendations of the “Each Home Counts” review. It outlines the standards and specifications for energy retrofitting of domestic buildings and covers the best practices for successful domestic retrofit projects.
The PAS 2035 Challenge
The purpose of creating PAS 2035 is to address the challenge of domestic building retrofitting, particularly for old buildings, which poses a significant challenge for energy retrofitting specialists globally. Therefore, retrofit experts need to have a complete understanding of the building’s condition and what energy efficiency measures would be suitable to achieve the best possible outcome. PAS 2035 details the processes and procedures for carrying out retrofit work on domestic buildings, including assessing the building’s condition, selecting and prioritizing energy efficiency measures, and monitoring and evaluating retrofit work.
In PAS 2035, the Retrofit Coordinator plays a vital role, responsible for coordinating with building owners and other parties involved in the retrofit project. Here’s a breakdown of the PAS 2035 standards for a domestic building retrofit project:
1. The Retrofit Coordinator conducts a comprehensive assessment of the building’s various aspects, as mentioned above. They may also request information from the owners on any potential performance issues, revise the Energy Performance Certificate (EPC), and perform a survey of the building. The retrofit coordinator then rates the building from A (low risk) to C (high risk).
2. Next, the Retrofit Assessor performs a Whole House Dwelling Assessment, which is more extensive for homes ranked with higher risks.
3. The Retrofit Designer then takes the report to select the best package of Energy Efficiency Measures (EEMs). Usually, the Retrofit Designer offers multiple improvement plans, which the Retrofit Coordinator presents to the client for approval.
4. The Retrofit Coordinator works with retrofit installers to provide them with information on each EEM. The Retrofit Installers are responsible for ensuring that the EEMs are installed and commissioned in compliance with PAS 2030.
5. Once the EEMs are installed, the Retrofit Coordinator collects all the necessary documentation and briefs the building owners on how to operate the EEMs.
6. The Retrofit Evaluator performs a Basic Evaluation of the installed EEMs in the building. If any issues are found, a detailed evaluation may follow, including recommendations for remedial work.
Conclusion
Infinity Energy offers Retrofit Coordinator services to our installer network and City and Guilds NVQ Level 2 training to comply with PAS 2035 requirements. Our sister company, Infinity Property Management, is already accredited to PAS 2035 and PAS2030:2019 requirements.
